The Transmission Control Protocol (TCP) [J88] is the most popular transport layer protocol in the Internet for reliable data transmission. It has had a significant impact on the performance and behavior of the Internet [TMW97]. However, it has been long known for its unsatisfactory performance in high bandwidth-delay product (BDP) networks. Such performance limitation comes from TCP's conservative congestion control algorithms which are unable to cope with the features of high BDP networks,
